Actually it is the motor that will be under powered. It will behave like a 2.5A motor. This won't harm either the motors or the board you just won't get the full amount of oomph out of the motor. And while you're probably wondering why not just give the boards more power, it's not that simple. They would if they could but the chips for this level of board can only handle so much load.
